Electrostatic Field Dust Removal Device

An electrostatic field dust removal device, wherein the electrostatic field dust removal device comprises:

• at least one negative electrode plate for releasing negative charges, wherein at least two first spike structures are arranged on each negative electrode plate of the at least one negative electrode plate, the at least two first spike structures are alternatively arranged on plate surfaces on both sides of said each negative electrode plate, respectively, and said each negative electrode plate releases the negative charges through tips of the at least two first spike structures;
• and
• at least one positive electrode plate, which is alternately arranged in parallel with the at least one negative electrode plate, for receiving the negative charges released by the at least one negative electrode plate, each positive electrode plate of the at least one positive electrode plate is correspondingly arranged with at least two second spike structures according to an arrangement of the at least two first spike structures on said each negative electrode plate;
• the plate surfaces of the each negative electrode plate and the each positive electrode plate are arranged as wavelike plate surfaces;
• and
• the each first spike structure and the each second spike structure are arranged at a center of a convex position or at a center of a concave position of the wavelike plate surfaces;
• wherein an electrostatic dust removal region is formed in such a way that the tips of the at least two first spike structures on the each negative electrode plate release the negative charges towards a plate surface of the positive electrode plate directly opposite thereto, a glow plasma region is formed in such a way that a flat surface of an opposite side plate surface of the plate surface where the at least two first spike structures on said each negative electrode plate are located releases the negative charges towards the tips of the at least two second spike structures on the positive electrode plate directly opposite thereto, and
• wherein waste gas flows between said each negative electrode plate and said each positive electrode plate and is alternately purified, wherein it is purified by corona in the electrostatic dust removal region and ionized in the glow plasma region.
